To all whom it may concern:

Be it known that'I, ROBERT WV. BA'NKs,

Jr., a citizen of the United States, residing at'Shreveport, in the Parish of Caddo and State of Louisiana, have invented certain new and useful Improvements in Razor- Blade Sharpeners, of which a specification. v V I V I This invention relates to an improved razor sharpener for sh arpe1'1ingthe blades of safety razors and the principal object of the invention is to provide a machine of the character described having an improved type of carriage and blade holder and improved means for slldably mountlng the carriage and reversing the position of the blade holder as the carriage moves back and forth upon the track to bring the blade into engagement with the sharpener.

Another. object of the invention isto pro vide an improvedmeans for mounting the sharpener.

Another object of the invention is to so construct this device that the sharpener may be pivotally mounted and thus conform. to

the position of the blade to insure proper en-- gagement ofthe blade and sharpener snare; further-so mount the sharpener that it 'may be removed and reversed in its position or i i the yoke may be removed when desired. The

a new one put in place.

Another object of the invention is to so construct this device that the position of the blade holder when moving along. the track Thisinvention is illustrated in the accompanying drawings, wherein Figure 1 is a top plan view of the improved razor blade sharpener.

Fig. 2 is a view showing the improved device in side elevation,

Fig. 3 is a longitudinal sectional view taken along the line 3-3 of Fig. 1.

Fig. 4 is a transversely sectional view taken along the line 4-4 of Fig. 1.

Fig. 5 is a sectional view taken along the line 5-5 of Fig. 1.

The frame of this razor honing and stropping machine is provided with side bars 10 the following is and 11 which have their end portions re duced to provide pins extending through openings formed in the end bars 12. Rods 13 which form tracks are passed through openings formed in the end bars 12 and carry securing nuts 1 1 which when tightened, will cause the end bars to be securely held in engagement with the side bars thus permitting the bolts. 13 to serve a double purpose, one being to serve as securing ore-E..-

means for the bars 10, 11- and 12 and the other being to serve as tracks as will be hereinafter brought out. A handle 15 is screwed into an opening formed in one of the end 1 ceive the pivot pin 1 of the plate 18 which plate carries a stone 19 upon one side'and a leather strop20fupon its opposite side. A clampingyoke 21 extends beneath the bars 16 and is provided with upstanding arms 22 holding the pivot pins in the sockets and" Cross bars 16 are provided with re- .75 I the side bars 10 and '11 and are provided'in-. termediate their lengthjwith sockets to re-:

terminating in ears 23 bymeans of which stropping and honing element which be termed the sharpening element will therefore be 'pivotally mounted and' will be limited in its pivotal movement by the tongues 24 extending from the cross bars 16 beneath the sharpening element.

The actuating carriage or main carriage 25 is provided with ears 26 slidably mountregisters with a wider slot 29 formed in a plate30 slidably connected with the wall 27 by tongues 31 and provided with teeth at the upper and lower edges of the slot 29 thus providing racks 32 and 33 selectively brought into engagement with the gear 3 1 through turning of the cam 35 carried by the wall 27 and extending through an opening 38 formed in the rack plate 30. A handle 39 is provided so that the actuating carriage or main carriage may be moved longitudinally upon the tracks 13 and pass beneath the sharpener carrier as shown in Fig. 3.

The auxiliary carriage or blade carrying carriage 40 is provided with ears 41 slidably connecting the auxiliary carriage with the tracks 13, resilient strips 42 being connected at their ends with the tongues 4land arched longitudinally so that they will engage the rods or tracks 13 and thus provide friction brakes yieldably resisting movement of the auxiliary carriage along the tracks. Thisauxiliary carriage 1s provided with upstanding arms 43 positioned outside the side bars of the frame and forming bearings to rotatably mount the shaft 44, the shaft extending through the slot 28 and carrying the gear 34 with which the racks 32 and 33 will be selectively brought into engagement. It will thus be seen that when the main carriage is moved longitudinally through the medium of the actuating handle 39, the shaft 44 will be first rotated until the gear 34 reaches the end of the rack with which it is in engagement and the auxiliary carriage will then be moved with the main carriage along the tracks 13 with the shaft 44 passing above the sharpener element. This shaft 44 carries a blade holding clamp 45 which will be securely held in engagement with the shaft 44 by the spring clip 46 and turned with the shaft thus reversing the position of the blade carried thereby when the shaft is rotated at the beginning of the longitudinal movement of the main carriage upon the track. An abutment finger 47 is rigidly mounted upon the shaft 44 and when the shaft rotates to swing the clamp from one position to another, the abutment finger will strike one of the guiding plates 48 thus preventing further movement of the blade clamp until the inner end of the guide strip is reached. The inner ends of these guide strips are curved as clearly shown in Fig. 2 and when the abutment finger 47 reaches the inner end of the strip upon which it is resting, it will follow the incline thus permitting the blade to be brought into engagement with the sharpening element. After passing across the sharpening element, the abutment finger will engage the inclined inner end of the second guiding strip and the blade will be lifted from the sharpening element. Upon reaching the end of the copies of this patent may be obtained for five cents each, by addressing the Commissioner 02 Eatents,

eases"? movement in this direction, the main carriage will be moved in the opposite direction and the shaft will then be rotated to reverse the position of the blade carrying clamp after which the auxiliary carriage will be carried longitudinally of the frame with the main carriage. This operation will be repeated until the razor blade is properly sharpened. The rack plate will of course be shifted according to whether the stone or strop is in use, it being moved to bring the holder toward the sharpener element with the edge of the razor blade toward the sharpener when the razor is being honed and the rack plate being moved to reverse the position of the blade holder and bring the same toward the sharpener with the sharp edge of the blade away from the sharpener when the blade is to be stropped. This sharpener by being pivotally mounted accommodates itself to the position of the blade thus bringing the entire edge of the blade into engagement with the sharpener element.

W hat is claimed is 1. A razor blade sharpening device comprising a frame, cross bars carried by said frame, a sharpener element including a carrier plate having pivot pins supported by said cross bars, a yoke extending beneath said cross bars and having arms extending upwardly to releasably hold the pivot pins in place, and blade holding means movably carried by said frame.

2. A sharpening device comprising a frame, cross bars. carried by said frame, a sharpener element having pins extending from opposite sides and supported upon said cross bars, a yoke extending beneath said cross bars and having side arms extending upwardly to engage the cross bars above the pins and releasably hold the pins in place,

and blade holding means movably carried by said frame for movement across the sharpener element.

In testimony whereof I aiiix my signature in presence of two witnesses.
